7 Claims.

This invention is concerned with a register for 'directing the passage of air into a room from a ue which carries the air, and through which it is moved either by natural movement or by forced circulation thereof. y

Registers of this character are usually placed in the wall of the room and-'while the more mod ern practice is to locate Such registers toward the ceiling of the room, they may be located at other positions. 'I'he air which passes' through the flue and thence through the register into a room is heated during the colder months of the year and may be cooled during the warmer months, the term applied to the tempering of the air being that it is ,eonditionedf and a room into which the air is directed is air conditionedv in accordance with the different temperatures at different seasons of the year. J

It is undesirable `that heated air should be directed upwardly into the room and toward the ceiling, particularly when the register is located adjacent the ceiling. On the other hand, it is undesirablethat colder air coming into the room should be directed downwardly by the register. Heated air naturally rises because of itslighter specific gravity and colder air will descend for the same reason.

The present invention is concerned with a register of novel construction wherein the air may be directed horizontally through the register into the room, or by small change and adjustment of` parts may havel its angle of direction changed either slightly above the horizontal or slightly below, the usual maximurnlimits both above and below the horizontal notV exceeding register is also provided with structure whereby it may be completely closed so that no air will pass from the ue into the room. The construc-` tion for attaining these advantages and results is one which is simple and comparatively inex- Fig. 2 is a partial end elevation and-partial verf f tical section showingthe register in closed po-v.

The

Like reference characters refer to like parts in the several gures of the drawing.

In the register structure a frame usually of rectangular shape is provided and as disclosed, the sides and ends of theregister are pressed or formed from sheet metal with vertical yface flanges! and inwardly extending flanges 2 at right angles thereto. Around the flanges 2 a second frame Bis provided of Z-bar material which is secured in place by spot `welding or other suit able means. A plurality of vertical vgrille bars i extend between the upper and lower horizontal flanges 2 and at their ends may be pivotallyv mounted on pintles and joinedto'gether in groups by la connection to they several plates 5 lying against `the upper side ofthe lower inwardly `ex-v tending flange 2, and which are held by screws 6 and leaf springs interposed between the headsl of lthe screws and the -under lsides, of the lower ange 2, the screws passing through slots in said flange 2 whereby a group of the bars may be tilted to one side or the other of a central vertical plane. However, this specific form of structure and of the adjustmentof the grille bars lis in no sense essential to our invention andthe bars may be, andofttimes in practice are, se-` cured at their ends without providing any means for adjustment thereof as described. The 'specie structure of the frame and grille bars as outlined is not to be considered as limiting the invention thereto in any respect, as the invention is applicable to many other specific forms of frame structure and, verticalA or` other typecf grille bars. l

The register is adapted to be installed at an opening in thewall `'l ,of the room and form an outlet for air passing upwardly through anaircarrying nue 8 which, in some instances, is closed at its uppery end immediately above the register and inothers may be continued upwardly to an upper room in ,the building. In any case,r air moves upwardly throughtheilue either through natural force or because of being blown or forced and will pass outwardly thro-ugh the register when the-same is open to permit such passage,

` Withour invention a sheet metal. plate ,3 is permanently secured by welding or, other permanent connections-to a depending leaf` li! of a hinge which extends substantially the full length of the register, said leaf having. a hinge con nection about hinge pin l I vto a second hinge leaf ,I2 which, together with a vertical positioned at bar I3 Iin frontof it, `is secured rtothe Lipper horizontal member of the frameA described, usualkly by Vscrews as shown. The plate 9' may' be In the structure shown, a member having'a' vertical leg I- is permanently secured at one end and at the rear side of the plate S. vertical slot l5 is out in the leg adaptedy to be traversed by the shank of a bolt or screw Il carried at the inner end of an operating handle l. The handle is pivotally mounted between its ends on pivot pin i8 carried at a side of the surrounding frame 3, and passes through a vertical slot in the face flange I at one end of the frame. The handle is accessible for manual operation and by pulling down on the outer free end of the handle the plate 9 may be swung from its closed position in Fig. 2 to the position in Fig. 3.

Varies i9 shown as two in number, though the number may be increased if necessary, extend lengthwise of and within the frame back of the bars 4 and are carried on flexible tapes 20, the tapes passing through said vanes at spacedapart points. Two of the tapes are shown used one adjacent each end of the register, and each at one end passes through the plate S and is provided with a stop at 2l' at the rear side of the plate. Also stops 2| are secured to the tape at cach side of a vane I9 at each place where the tape passes therethrough. The rear or inner sections of the tape from the plate il pass downwardly and forwardly through rear portions of the vanes I9 and around rods 22 located between pairs of the bars ll near their lower ends, and are then turned back upon themselves, extending upwardly through the front portions of the vanos IS, and at their upper ends are clamped between the plate I3 and the upper leaf I2 of the hinge previously described. The stops 2l for convenience may be sheet metal clips bent around each side of the tape and attached thereto.

When the air-deileoting plate 8 is in its closed position, as in Fig. 2, the tapes 20 are slackened and the vanes I9 may occupy a position approaching or toward the Vertical being located between the front side of the plate 3 and the rear edges of the vertical grille bars 4. On manually operating the handle I6, the tapes have their slack taken up and are tautenedand automatically move the vanes to the position shown in Fig. 3, wherein an upper vane is disposed in aplane back of a lower vane and the forward portions of said vanes are located in substantially horizontal planes. The rear portions of the vanes as shown are curved in a downward direction so that air rising vertically or being forced vertically in the nue B coming to said curved portions of the vanes has its direction changed and is directed horizontally outward through the bars 4 by reason of the horizontal positions of the forward portions of the vanes I9.

The angular position of the vanes may be altered by changing the positions of the stops 2I at the rear side of the plate 9, also by slightly moving the outer end of the operating handle IG upwardly from its lowermost dotted linenposition shown in Fig. 3. .The position of the vanes may be changed so that the forward portions thereof will be inclined at a slight angle to the horizonascisse tal. The vanes automatically occupy the desired position for directing the air horizontally into the room from a vertical flue through which the air is coming to the vanes when the grille is opened for air passage.

The construction described is one which is easily made and assembled and in which a very practical and 'desired eiicient direction of the air through a room into a grille is attained. The invention is capable of embodiment in many other forms of structure and is not to be considered as limited to the structural detail specifically disclosed. The invention is dened in vthe appended claims and is considered to be comprehensive of all forms of structure coming within the scope ofthe claims.
